does the active x factor catalyses the conversion of fibrinogen to fibrin or prothrombin to thrombin

Coagulation can be activated by two different pathways, but both pathways converge on:Select one alternative:thrombinFactor XprothrombinFactor Xa

the active x factor catalyses the conversion of what

Name the enzyme that catalyzes the reaction that converts fibrinogen to fibrin.Multiple ChoiceProthrombin activatorThrombinTissue thromboplastinPlasmin

Which factors contribute to the activation of thrombin in the coagulation cascade, leading to the conversion of fibrinogen to fibrin and clot formation, and what regulatory mechanisms promote positive feedback of coagulation?Group of answer choicesFactors VII, VIII, IX, X, and XI; Feedback activation by thrombin.Factors IX, X, XI, XII, and XIII; Feedback inhibition by fibrin.Factors II, V, VIII, X, and XIII; Feedback inhibition by fibrin.Factors II, V, VII, X, and XII; Feedback activation by thrombin.

Assertion: Fibrins are produced by the conversion of inactive fibrinogens in the plasma, in the presence ofenzyme thrombin.Reason: Plasma without fibrinogen and blood corpuscles is called serum
